It could be. I thought it was on the Thames, but Im probably wrong and your location sounds more plausible

No, definitely not that one. That looks to be the same as in the video earlier in this thread. The one Im thinking of goes back probably twenty years before the introduction to the market of the big Lorry Loaders(Hiab, Palfinger, etc..). The one I'm thinking of involved Mobile Cranes. Im sure it was the Thames and they were lifting out one of the barges that they used for sea disposal.

Wow, that is really quite a worrying video!
It's surprising how easy cranes can go over if the operator doesn't know what he is doing, just last week we were using a 120 ton crane to lift 12 tons of generator over a building on a 20 metre reach. The boom was out over the rear of the crane chassis and the front stabiliser legs lifted 3 feet off the ground like a giant see-saw  Thankfully she settled back down after a while but it was pretty unnerving.
It turned out that the sub-contractor had messed about with the load sensors rather than send a larger crane.   |

Shouldnt happen really load sensors or not, If the operator had a true load weight then the charts should give the load v distance numbers.
That said we had a 15k set of forks lift at the rear a few months ago lifting a load off the back of a 40 footer, and that unit had its gross weight stencilled on the side /cough. I only play at it really, max is around 3.5 and though we use alot of boom height the horizontal distance from the cranes never very far. Biggest was the structures installation out in Norway, had a Demag CC2800 crawler but wasnt involved in that part of that project so only spectating. 3 Landrovers |

To give the operator his dues, he controlled the situation well if not safely. Unlike in Europe, this lift was in West-Africa with a 22 year old crane and very little legislation about crane testing/certification.
I believe he was lifting at 60 metres of height but it was rather touch and go... That Demag is a big bit of kit indeed! |
